Question

Hydrogen is the only element whose three common isotopes have been given different names.

A. True
B. False

Answer 1

It is true that hydrogen is the only element whose three common isotopes, protium (¹H), deuterium (²H or D), and tritium (³H or T), have distinct names.

Step-by-step explanation:

The statement that hydrogen is the only element whose three common isotopes have been given different names is true. Hydrogen's isotopes include protium (1H), deuterium (2H or D), and tritium (3H or T). Protium, which has one proton and no neutrons, is the most abundant isotope. Deuterium has one proton and one neutron, and tritium has one proton and two neutrons. The common names for these isotopes are often used alongside their chemical symbols.
